The last project I did drawings for involved brass models made in China. I provided scale drawings (not RR general arrangement drawings that are seldom to scale) with a few measurements on them . . .
I can't speak for many railroads' practice, but the SP, UP and PFE general arrangement drawings I have seen are most certainly scale drawings, as one can verify by checking details, and are quite carefully done. The good Mr. Vlk referred to them as "cartoons," and perhaps on some railroads that was true, but certainly not for the examples cited.
Nor for those I've seen from the Santa Fe files. General arrangement drawings for Santa Fe freight cars were highly detailed and drawn to exact scale. Their only shortcoming was that they typically did not show the air brake componenes and brake rigging, as those were shown on other drawings.
